What does "when humans think, God laughs" mean?

"When humans think, God laughs." This now widely circulated aphorism is the entire understanding of life and the entire human world. The general idea is that as a limited human being within a limited life, They don't understand their own insignificance and ignorance, but they like to think beyond the infinite and act arrogantly. Because of people’s own cleverness, and also because of their own smallness and insignificance. The more we think about it, the closer we think we are to the truth, only to find that we have been fooled by God.

This is a vicious circle that cannot be broken under the constraints of social ethics and morality, and it is also a narrow and humble part of human nature. Since he couldn't get rid of it, he began to doubt and deny it, and eventually fell into a human tragedy. The tragedy lies not in the result, but in the fact that humans have never been able to transcend themselves during the entire process.

Extended information:

"When humans think, God laughs" is an ancient Hebrew proverb. Milan Kundera won the Jerusalem Literature Prize in May 1985. This is a line from the speech delivered at the ceremony when the award was awarded. This article is an article in Milan Kundera's "The Art of the Novel" and is also included in "The Unbearable Lightness of Being". Compared to God, human life is only once and cannot be repeated or used for reference. Human cognition is also limited, so the thinking made by human beings is narrow, and our thinking sometimes makes us lost.
